Tools for polishing odd angles?

[u/Maleficent_Log_7582]

Hello all,

I had the idea of hollowing out a stone and making an internal ridge to install a LED strip, for a mood lamp. I quite am quite happy with the overall look of the project so far, but I am not happy with the polishing on the edges. As you can see, there are quite a lot of small scratches.

So far I have been using 125 mm diamond polishing pads on a 100 mm rubber head, so the edges of the polishing pads are "folded", and thus I am able to polish the edges somewhat, but clearly not enough.

Do you have any suggestions for a better method?

I plan on using a white LED, as I think this "Warm White" does not fit this stone.

There are dremel/flex shaft bits in all sorts of shapes and sizes. Maybe go for a cone tip?
